Learning Jakarta Struts 1.2: a concise and practical tutorial

By: Stephan Wiesner

Overview of this book

<p>Jakarta Struts is an Open Source Java framework for developing web applications. By cleanly separating logic and presentation, Struts makes applications more manageable and maintainable.<br />Since its donation to the Apache Foundation&nbsp; in 2001, Struts has been rapidly accepted as the leading Java web application framework, and community support and development is well established.<br /><br />Struts-based web sites are built from the ground up to be easily modifiable and maintainable, and internationalization and flexibility of design are deeply rooted. Struts uses the Model-View-Controller design pattern to enforce a strict separation between processing logic and presentation logic, and enables efficient object re-use.<br /><br />The book is written as a structured tutorial, with each chapter building on the last. The book begins by introducing the architecture of a Struts application in terms of the Model-View-Controller pattern. Having explained how to install Jakarta and Struts, the book then goes straight into an initial implementation of the book store. The well structured code of the book store application is explained and related simply to the architectural issues.<br /><br />Custom Actions, internationalization and the possibilities offered by Taglibs are covered early to illustrate the power and flexibility inherent in the framework. The bookstore application is then enhanced in functionality and quality through the addition of logging and configuration data, and well-crafted forms. At each stage of enhancement, the design issues are laid out succinctly, then the practical implementation explained clearly. This combination of theory and practical example lays a solid understanding of both the principles and the practice of building Struts applications.</p>

Chapter 2. Hello Struts

This chapter takes you through the installation process of Tomcat and Struts. Once set up, we work through a simple example, so that you can start experimenting with an executable application as soon as possible.

It is assumed you already have Java installed. If not, get the Enterprise Edition SDK from http://java.sun.com.

2.1 Tomcat Server Installation

Tomcat 5.5.9 (http://jakarta.apache.org/tomcat/) is used for all the examples in this book. The examples should work with all versions of the server, but beginners are urged to use the same version or later to eliminate a potential source of errors. In any case, you should use at least version 4.x.

Many readers would like to ask why Tomcat server was chosen from all the available servers. Some of the reasons for choosing Tomcat are that it is free, you can view the source code, and it is very widely used. Sun Microsystems recommends Tomcat as the reference implementation for servlets and JSPs. Furthermore, if we had shown...
